Adjustable loop with locking knot

ABSTRACT

Systems, devices, and methods for soft tissue repair are generally provided and they generally involve the use of surgical filaments that are configured in a variety of manners to minimize and/or eliminate the tying of knots during a surgical procedure. Moreover, systems and devices described herein can provide for a reversible locking knot, which allows for additional tension to be applied to the repair if adjustments are required after the construct has been locked. The reversible locking knot can be “flipped” or actuated without requiring the knot to be untied and then retied. Further, systems and devices described herein can additionally be used to associate implantable bodies and suture constructs within a bone to secure soft tissue while not restricting the relative movements of operative sutures once the implantable body has been deployed.

The present application is a divisional of and claims priority to U.S.patent application Ser. No. 16/033,549, filed Jul. 12, 2018, andentitled “Adjustable Loop with Locking Knot,” the contents of which ishereby incorporated by reference in its entirety.

FIELD

The present disclosure relates to systems, devices, and methods forsecuring soft tissue to bone, and more particularly a suture constructthat includes a self-locking knot, a selectively adjustable loop, and afixed eyelet.

BACKGROUND

A common injury, especially among athletes and people of advancing age,is the complete or partial detachment of tendons, ligaments, or othersoft tissues from bone. Tissue detachment may occur during a fall, byoverexertion, or for a variety of other reasons. Surgical interventionis often needed, particularly when tissue is completely detached fromits associated bone. Currently available devices for tissue attachmentinclude screws, staples, suture anchors, and tacks. Further, currentlyavailable devices for patients of advancing age can be particularlyinsufficient due to soft and weak bones leading to inadequatesuture-to-anchor fixation.

During tissue repair procedures, such as shoulder rotator cuff andinstability procedures, arthroscopic knot tying is a common practice. Insome common procedures, an anchor loaded with suture is first disposedin bone. The suture is normally slidably attached to the anchor throughan eyelet or around a post or similar feature such that a single lengthof suture has two free limbs extending from the anchor. One limb of thesuture can then be passed through soft tissue to be repaired (e.g.,tendon, labrum). The two ends of the suture can then be tied to eachother, thereby capturing the soft tissue in a loop with the anchor. Theloop can be subsequently collapsed to draw the tissue towards theanchor, and thus the bone.

Surgeons often use a surgical sliding knot, such as a Tennessee Slideror a Duncan Loop, to tie the suture ends together to form the loop. Aforce can then be imparted on the sliding knot to advance it towards thebone, which, in turn, collapses the loop to draw the tissue towards theanchor and the bone. Once the knot, and thus the tissue, is at a desiredlocation with respect to the anchor and bone, the location of the knotcan be fixed in place using techniques known to those skilled in theart. For example, one customary way to secure the location of the knotis to tie a number of half hitches or other knots on the suture,proximate to the knot, to hold the location of the knot. Such aconfiguration can prevent the knot from loosening or sliding. If knotsare not formed, a conventional sliding knot does not typically provideappropriate protection against loosening or slippage, especially whentension is placed primarily on the limbs of the loop. In some instances,a surgeon may at least form three reversed half hitches on alternatingposts or limbs of the suture, proximate to the knot, to prevent the knotfrom loosening or slipping.

A person skilled in the art, however, will recognize that even beforeone or more half hitches or the like are formed proximate to the slidingknot, there exists a potential for the sliding knot to slip, causing theloop to enlarge and the desired location of the tissue be lost. This hasbeen referred to as loss of “loop security,” and can reportedly occureven in the hands of very experienced surgeons. Sometimes, evenfully-tied knots may slip. Still further, in addition to “loop security”issues, many conventional knots can have an overall size that may beobstructive or intrusive, especially in tight joints, which may damagecartilage or other tissue by abrasion with the knot.

The types of anchors used in conjunction with the aforementioned typesof tissue repairs include both soft anchors, which are often made out offilament or similar materials, as well as more traditional hard anchors.Non-limiting examples of some such soft and hard anchors are providedbelow in the detailed description either by being described or beingincorporated by reference, and many different configurations of the sameare known to those skilled in the art.

Whether using hard or soft anchors, some steps often involved in arepair process can include: (1) securing an anchor at a desired locationwith respect to bone to which tissue is to be attached (e.g., within oradjacent to a bore in a bone); (2) associating one or more operativeand/or accessory suture(s) that are in some manner coupled to the anchorwith the tissue to be attached to bone; (3) sliding or otherwisemanipulating one or more of the operative and/or accessory suture(s) toperform a repair procedure that results in tensioning the tissue to drawthe tissue to a desired location with respect to the bone; (4) securingthe repair, including the tensioned tissue, at the desired location withrespect to the bone; and (5) removing operative and/or accessory suturesfrom the surgical site as appropriate. When the anchor is a soft anchor,the step of securing an anchor at a desired location can includedeploying an anchor, such as by expanding or otherwise actuating theanchor. While some of the aforementioned steps, or other steps performedduring a repair procedure, may be able to performed simultaneously, itcan often be desirable to separate each step, and their relatedfunctional outputs, so that suture(s) and other components of the repair(e.g., the anchor, tissue, etc.) do not get trapped, caught, becomedifficult to maneuver, etc.

A number of other complications also exist with respect to currenttissue repair procedures. For example, it is desirable to minimize asize of the components being implanted in the body (e.g., the anchor,the suture(s), etc.). Further, existing suture implant systems canrequire substantial forces, on the order of about 40 pounds of force toabout 50 pounds of force, to fully insert implants (e.g., anchors),which can increase the difficulty of soft tissue repair procedures, forinstance, by putting undesirable stress on tissue, bone, etc. Stillfurther, some existing implant systems often require the use of one ormore sutures that are not easily removed from the surgical site aftercompletion of procedure even though the suture(s) is not functionallyholding any tissue, bone, or key part of the system in place. Yetanother complication with existing systems is that some systems are notversatile such that they can allow a user to reverse actions once taken.For example, in some systems, once a suture loop has been collapsedand/or locked into a location, there is no easy way to expand the loopand/or unlock its location.

Accordingly, there is a need for systems, devices, and methods for usein soft tissue repair that are robust and strong, yet minimize oreliminate the number and size of knots to be tied by a surgeon,particularly during arthroscopic repair procedures. There is also a needfor systems, devices, and methods that reduce the amount of force neededto secure the location of an implant with respect to a bone whilekeeping the location of the implant, suture, and related tissue assecure as possible. There is a further need for systems, devices, andmethods that provide enhanced maneuverability, adjustability,versatility, and selective locking of a suture construct and its relatedcomponents.

SUMMARY

Systems, devices, and methods for soft tissue repair are generallyprovided and they involve the use of surgical filaments that areconfigured in a variety of manners to minimize and/or eliminate thetying of knots during a surgical procedure. The systems and devicesdescribed herein provide superior strength for use in a number ofdifferent surgical procedures, such as rotator cuff and instabilityrepair procedures, and other types of tendon and tissue repairprocedures. They also allow for attachments that have a lower profilethan existing systems and devices, which allows for the filaments tobecome associated with tissue, for instance by passing the filamentsthrough the tissue or wrapping the filaments around the tissue, withminimal trauma to the tissue and less space being taken up by theoverall construction. This results in systems and devices that can beassociated with tissue atraumatically to secure the tissue in a knotlessmanner.

Moreover, systems and devices described herein provide for a reversiblelocking knot (the knot often being pre-tied such that a surgeon does nothave to tie the knot during a procedure), which can allow for additionaltension to be applied to the repair if adjustments are required afterthe construct has been locked. The reversible locking knot can be“flipped” or actuated without requiring the knot to be untied and thenretied. More particularly, the reversible locking knot allows anassociated collapsible loop to be selectively locked and unlocked. Asprovided for herein, when the reversible locking knot is in an unlockedposition, the collapsible loop can have a size of an opening defined bythe loop adjusted, i.e., a diameter of the collapsible loop can be madebigger and smaller. When the reversible locking knot is in a lockedposition, the size of the opening defined by the collapsible loop can bemaintained, i.e., the diameter of the loop is fixed. Further, systemsand devices described herein can additionally be used to associateimplantable bodies (e.g., anchors) and suture constructs within a boneto secure soft tissue while not restricting the relative movements ofoperative sutures once the implantable body has been deployed orotherwise positioned with respect to bone.

In one exemplary embodiment of a suture construct, the constructincludes a filament loop having a slidable knot, an adjustable limb anda fixed loop that each extend from the slidable knot, and an implantablebody coupled to the filament loop. The filament loop defines an openingthat has an adjustable diameter, and the adjustable limb is configuredto adjust the adjustable diameter of the opening when tension is appliedto the adjustable limb to move the adjustable limb with respect to theslidable knot. The fixed loop also defines an opening, but the openinghas a fixed diameter. Further, the fixed loop has a first, unlockedconfiguration and a second locked configuration. When the fixed loop isin the first, unlocked configuration, the adjustable limb is movablewith respect to the slidable knot and the adjustable diameter of thefilament loop is adjustable. When the fixed loop is in the second,locked configuration, the adjustable limb is prevented from moving withrespect to the slidable knot such that the adjustable diameter of thefilament loop is fixed.

In some embodiments, a single filament can be used to form the filamentloop, the adjustable limb, and the fixed loop. The implantable body canhave a variety of configurations. For example, the implantable body caninclude a filament (e.g., a soft anchor, as provided for herein orotherwise known to those skilled in the art). Alternatively, oradditionally, the implantable body can include at least one corticalbutton. In some such embodiments, there can include two corticalbuttons.

The fixed loop can be rotatable with respect to the slidable knot suchthat rotation of the fixed loop with respect to the slidable knot movesthe fixed loop from the first, unlocked configuration to the second,locked configuration. The second, locked configuration can be reversiblesuch that the fixed loop can be moved from the second, lockedconfiguration to the first, unlocked configuration. The adjustable limbcan pass through the slidable knot. It can have a substantially straightconfiguration within the slidable knot when the fixed loop is in thefirst, unlocked configuration, and a tortious configuration within theslidable knot when the fixed loop is in the second, lockedconfiguration.

One exemplary embodiment of an implant includes a soft anchor that isconfigured to be fixed in bone and is formed of a flexible construct, afilament that extends from the soft anchor, and a suture attachment loopthat is formed from the filament. The soft anchor has an unstressedconfiguration with a first length and a first diameter and an anchoringconfiguration with a second length and a second diameter. The secondlength is less than the first length, and the second diameter is greaterthan the first diameter. The filament that extends from the sutureanchor is configured to apply tension to the soft anchor to move it fromthe unstressed configuration to the anchoring configuration, and thesuture attachment loop defines an opening that has a fixed diameterconfigured to receive a suture through the opening.

The suture attachment loop can be configured to slidably receive suturethrough it. The filament can include a locking knot. The locking knotcan be configured such that it has a first configuration in which thelocking knot permits the soft anchor to be adjusted and a secondconfiguration in which the locking knot locks the configuration of thesoft anchor. In some embodiments, the filament can include an adjustableanchor loop. In some such embodiments, the soft anchor can be disposedon the adjustable anchor loop and the filament extending from the softanchor can be configured to adjust the diameter of the adjustable anchorloop.

One exemplary embodiment of a method of using a suture repair constructincludes tying a first limb of a suture repair construct about a portionof an adjustable loop of the suture repair construct to set a size of anopening defined by an eyelet of the suture repair construct. The size ofthe opening defined by the eyelet is adjustable prior to tying the firstlimb of the suture repair construct about the portion of the adjustableloop. The method further includes tying the eyelet about a second limbof the suture repair construct to form a lockable knot, with the secondlimb of the suture repair construct being operable to control a size ofan opening defined by the adjustable loop. The second limb is configuredto slide within the lockable knot after the eyelet is tied about thesecond limb.

The method can further include disposing an operative suture in theeyelet such that a portion of the operative suture is disposed onopposed side of the eyelet, and manipulating the operative suture to tiethe eyelet about the second limb of the suture repair construct to formthe lockable knot. In some embodiments, the method can includetensioning the first limb of the suture repair construct to collapse thesize of the opening defined by the eyelet prior to tying the first limbof the suture repair construct about a portion of the adjustable loop toset a size of the opening defined by the eyelet. The method can alsoinclude tensioning the second limb of the suture repair construct tocollapse the size of the opening defined by the adjustable loop aftertying the eyelet about the second limb to form the lockable knot.

In some embodiments, the method can include coupling the suture repairconstruct to a suture anchor. Many different types of anchors can beused, but in some such instances, the anchor can include a soft anchorthat is configured to be fixated in bone and can be formed of a flexibleconstruct. The soft anchor can have an unstressed configuration with afirst length and a first diameter and an anchoring configuration with asecond length and a second diameter. The second length can be less thanthe first length and the second diameter can be greater than the firstdiameter. In some such embodiments, the method can include inserting thesoft anchor in a bone, threading at least a portion of the operativesuture through a portion of tissue, tensioning the second limb to movethe anchor from the first configuration to the second configuration, andtensioning the eyelet to move the lockable knot from a first, unlockedconfiguration to a second locked configuration. Many different resultscan be achieved by tensioning the eyelet to move the lockable knot fromthe first, unlocked configuration to the second, locked configuration,including, by way of non-limiting example, causing a tendon coupled tothe adjustable loop of the suture repair construct to be substantiallyfixed at a desired location. The method can further include manipulatingthe eyelet to move the lockable knot from the second, lockedconfiguration to the first, unlocked configuration. Many differentresults can be achieved by manipulating the eyelet to move the lockableknot from second, locked configuration to the first, unlockedconfiguration, including, by way of non-limiting example, allowing adiameter of the adjustable loop of the suture repair construct to beadjusted after previously having been fixed when in the lockedconfiguration.

One exemplary method for manufacturing a suture construct involves usinga single piece of suture that has a first terminal end and a secondterminal end. The method includes forming an overhand knot on a limb ofthe single piece of suture, with the overhead knot being in anuncollapsed configuration such that an opening is formed by the limb,and inserting the second terminal end of the suture through the openingof the overhand knot to create a sliding loop. The method furtherincludes inserting the first end of the suture through the opening toform an eyelet, and collapsing the overhand knot such that each of thesliding loop, the eyelet, the first end, and the second end extend fromthe collapsed overhand knot. In the resulting configuration, a size ofthe sliding loop is adjustable by the second end and the size of theeyelet is adjustable by the first end.

In some embodiments, the method can include tying a half-hitch knotaround a portion of the single piece of suture with the eyelet to form alock. The lock can be configured such that upon actuation of the lock, asize of an opening defined by the sliding loop is fixed. The method canalso include threading a soft anchor onto the sliding loop.

DETAILED DESCRIPTION

Certain exemplary embodiments will now be described to provide anoverall understanding of the principles of the structure, function,manufacture, and use of the device and methods disclosed herein. One ormore examples of these embodiments are illustrated in the accompanyingdrawings. Those skilled in the art will understand that the devices andmethods specifically described herein and illustrated in theaccompanying drawings are non-limiting exemplary embodiments and thatthe scope of the present invention is defined solely by the claims. Thefeatures illustrated or described in connection with one exemplaryembodiment may be combined with the features of other embodiments. Suchmodifications and variations are intended to be included within thescope of the present invention. Further, in the present disclosure,like-numbered components of the embodiments generally have similarfeatures, and thus within a particular embodiment each feature of eachlike-numbered component is not necessarily fully elaborated upon. Sizesand shapes of the systems and devices, and the components thereof, candepend at least on the anatomy of the subject in which the systems anddevices will be used, the size and shape of components with which thesystems and devices will be used, and the methods and procedures inwhich the systems and devices will be used.

The figures provided herein are not necessarily to scale. Still further,to the extent arrows are used to describe a direction a component can betensioned or pulled, these arrows are illustrative and in no way limitthe direction the respective component can be tensioned or pulled. Aperson skilled in the art will recognize other ways and directions forcreating the desired tension. Likewise, while in some embodimentsmovement of one component is described with respect to another, a personskilled in the art will recognize that other movements are possible. Byway of non-limiting example, in embodiments in which a filament ispassed through itself to form a sliding post, movement described withrespect to the inner portion (i.e., the sliding post as discussedherein) moving relative to the outer portion can likewise involvemovement of the outer portion with respect to the inner portion. Asprovided for herein, a size of an opening defined by a collapsible loopis sometimes described as having a diameter. A person skilled in the artwill recognize that just because the term “diameter” is used to describea loop, it does not mean that the loop has a fully circular shape.Because suture used to form the loop is flexible, the loop can take on avariety of shapes that may or may not be circular in nature.Accordingly, use of the term “diameter” by no means limits a shape of acollapsible loop and/or an opening defined by the collapsible loop. Tothe extent the present disclosure describes that a diameter increases ordecreases, it merely is reflecting the fact that a size of the openinghas changed and that an area defined by that loop has increased ordecreased, respectively. Additionally, a number of terms may be usedthroughout the disclosure interchangeably but will be understood by aperson skilled in the art. By way of non-limiting example, the termssuture and filament may be used interchangeably.

Systems, device, and methods for soft tissue repair are provided thatallow for added strength and versatility, without adding unnecessarybulk, to the repair construct. More particularly, the presentdisclosures are directed to a suture repair construct that includes avariety of features formed along the construct. These features includean adjustable loop that can be selectively collapsed to perform taskslike drawing tissue towards bone, an adjustable sliding-locking knotthat helps form the adjustable loop, and an eyelet having a fixeddiameter, but being configured to be manipulated (also described as“flipped” herein) to move from a position in which it sets a location ofthe adjustable sliding-locking knot, and thereby fixes a size of anopening of the adjustable loop, and a position in which it allows theadjustable sliding-locking knot to be moved, and thereby allowing a sizeof the opening of the adjustable loop to be moved. Notably, the abilityto selectively unlock and lock the eyelet, and thus the adjustablesliding-locking knot and the adjustable loop, allows for selectiveadjustments to the location of portions of the construct and/or thetissue with respect the bone without having to untie, tie, and/or retiea knot. In some instances, the suture repair construct may be formedfrom a single suture or filament, although multiple suture or filamentscan also be used. The suture repair construct itself can be coupled to asuture anchor and then used in conjunction with a suture repairprocedure. Suture anchors of most any type can be used in conjunctionwith the disclosure suture repair construct, including hard anchors andsoft anchors. The present disclosures provide the benefits of enhancedversatility and strength, while also not restricting the relativemovements of suture associated with the overall system and repair.

FIG. 1 provides one exemplary embodiment of an implant 10 having asuture construct 20, the suture construct 20 having a separate,operative suture 40 associated therewith. The construct 20 is a singlelength of filament or suture extending between two terminal ends 20 a,20 b, also referred to as a limb of suture, with the filament beingmanipulated to have operative elements formed on or otherwise associatedwith the filament. The illustrated operative elements of the construct20 include a filament loop or selectively adjustable loop 22, a fixedloop or eyelet 24, and an adjustable sliding-locking knot 60. As shown,each of these operative elements are formed from the same filament,although, as discussed below, the suture construct 20 can be formed froma plurality of sutures, in which case the operative elements may or maynot be formed from the same filament.

The selectively adjustable loop 22 is defined, at least in part, by theadjustable sliding-locking knot 60. As shown, the loop 22 forms anopening 26 having a diameter that can be adjusted. More particularly,application of a force in a direction F to a post 34 of the filament cancollapse a size of the opening 26 of the loop 22, i.e., its diameter. Inthe illustrated embodiment, applying a force in the direction F to thepost 34 causes the filament to slide with respect to the adjustablesliding-locking knot 60 in the direction F, thereby decreasing a size ofthe opening 26, i.e., shrinking its diameter. In some embodiments, theadjustable sliding-locking knot 60 can be moved to adjust the size ofthe opening 26. For example, the configuration can be such that applyinga force in an approximately opposite direction to the direction F cancause the knot 60 to advance in that opposite direction, towards adistal terminal end 22 t of the loop 22 as shown, to collapse a size ofthe opening 26. In some configurations, applying a force in thedirection F to the post 34 of the filament can cause the knot 60 toadvance in the aforementioned opposite direction, towards the distalterminal end 22 t of the loop 22, in a ratchet-like or incrementalmanner. A person skilled in the art will recognize a number of ways bywhich the selectively adjustable loop 22 can have the size of itsopening 26 adjusted, including increasing its size if desired.

The eyelet 24 is also defined, at least in part, by the adjustablesliding-locking knot 60. As shown, the eyelet 24 extends in a directionapproximately opposite to the direction the adjustable loop 22 extendsfrom the adjustable sliding-locking knot. While the formation of theeyelet 24 is described in greater detail with respect to FIGS. 3A-3E,generally the filament that is used to form the eyelet 24 can bemanipulated so that an opening 28 defined by the eyelet 24 has a desiredsize, also referred to as a diameter of the eyelet 24, and then thatsize is fixed so that it cannot be easily adjusted during use of theconstruct 20 during some types of procedures. Prior to fixing a size ofthe opening 28 of the eyelet 24, the diameter of the eyelet 24 can beadjusted. In the illustrated embodiment of FIG. 1, the eyelet 24 is in alocked configuration such that the size of the opening 28 cannot beeasily adjusted. More particularly, the sliding-locking knot 60 isformed in a manner that both sets a size of the diameter of the eyelet24 while also allowing the post 34 to be manipulated to change a size ofthe diameter of the adjustable loop 22.

An operative or accessory suture 40 can be threaded through the eyelet24 such that the operative suture is freely slidable relative to theconstruct 20. While the operative suture 40 can be coupled to otherotherwise associated with the construct 20, typically via the eyelet 24,in a number of manners, in the illustrated embodiment a first terminalend 40 a of the operative suture 40 is disposed on one side of theeyelet 24 and a second terminal end 40 b of the operative suture 40 isdisposed on an opposite side of the eyelet 24 with a portion of thesuture 40 disposed between the terminal ends 40 a, 40 b passing throughthe eyelet 24. As described in greater detail below, and as also knownby those skilled in the art, the operative suture 40 can be used toperform one or more of a variety of tasks during any number of surgicalprocedures, including but not limited to manipulating any of the implant10, the suture construct 20, and/or an anchor 80 associated therewith toposition any of them in desired locations, to secure tissue to desiredlocations, to adjust their configurations in desired manners, etc.

While the suture construct 20 can be used as a stand-alone implant, inthe illustrated embodiment the implant 10 includes an anchor 80associated with the suture construct 20. More particularly, the anchor80 is coupled to the selectively adjustable loop 22 so that the anchor80 and construct 20 can be used together to secure tissue to bone, or toperform other types of repairs made possible by the present disclosures.As shown, the anchor 80 is a soft anchor that is threaded onto theadjustable loop 20 using techniques known to those skilled in the art(e.g., passing the loop 22 through the anchor 80, forming the anchor 80onto the loop 22, etc.). Soft anchors are generally flexible in natureand can be formed from a flexible filament or from a polymeric materialin the form of, for example, a sleeve. Such soft anchors, whichtypically are non-metallic, can include one or more openings to allow atleast a portion of the adjustable loop 22 to pass into and/or throughthe anchor. Soft anchors can have an unsettled or unstressedconfiguration, as shown in FIG. 1, which can be used for deployment tothe surgical site, and an anchoring configuration, as shown in FIG. 2,which can be used for fixating the anchor following deployment at thesurgical site. As further illustrated in FIG. 2, the construct 20 can belocked within the bore by reducing the diameter of the adjustable loop22 to expand the anchor 80 and the knot 60 can be locked to fix theconfiguration of the anchor 80. Ways by which the knot 60 can be lockedare described in greater detail below.

In the illustrated embodiment, the soft anchor 80 can be moved from theunstressed configuration to the anchoring configuration by applyingforce in the direction F on the post 34 to collapse the adjustable loop22, which in turn can cause the soft anchor 80 to actuate from theunstressed configuration to the anchoring configuration, as shownbetween FIGS. 1 and 2. A person skilled in the art, in view of thepresent disclosures, will understand a variety of other ways by whichthe soft anchor 80 can be advanced to the anchoring configuration to setits position with respect to a bone. The transition of a soft anchorfrom the unstressed configuration to the anchoring configurationtypically alters the dimensions of the anchor, such as a length and/ordiameter of the anchor. By way of a non-limiting example, a diameter ofa soft anchor in its anchoring configuration, which may also be referredto as a second or actuated diameter of the soft anchor, can beapproximately in the range of about 10% greater to about 80% greaterthan the diameter in the unstressed configuration, which may also bereferred to as a first or initial diameter. In one embodiment, thesecond diameter can be about 20% greater than the first diameter of thesoft anchor. Similarly, by way of further non-limiting example, a lengthof a soft anchor in its anchoring configuration, which may also bereferred to as a second or actuated length, can be approximately in therange of about 20% less to about 80% less than a length of the softanchor in its unstressed configuration, which may also be referred to asa first or initial length. In one embodiment the second length can beabout 50% less than the first length.

Many different types and configurations of soft anchors can be used inlieu of the soft anchor 80. A person skilled in the art, in view of thepresent disclosures, will recognize many other feasible soft anchorsthat can be used in conjunction with the suture construct 20, and theother suture constructs provided for herein (e.g., constructs 120, 220,220′, 320) or otherwise derivable from the present disclosures. Somenon-limiting examples of such soft suture anchors are described in U.S.Pat. No. 9,345,567 to Sengun, the content of which is incorporated byreference herein in its entirety. Likewise, all types of hard anchorsmay also be used in lieu of the soft anchor 80. A person skilled in theart will recognize the many different types of hard anchors that existand can be used in conjunction with the present disclosures, and thus amore elaborate description of such anchors is unnecessary. Further,while this paragraph describes that other soft and hard anchors can beused in lieu of the soft anchor 80, a person skilled in the art, in viewof the present disclosures, will understand ways by which multipleanchors can be used in conjunction with one or more suture constructs(e.g., the constructs 20, 120, 220, 220′, and 320), without departingfrom the spirit of the present disclosure, and thus other soft and hardanchors can also be used in conjunction with the soft anchor 80 ifdesired.

The suture construct 20 and the operative suture 40, as well as othersuture constructs and other sutures provided for herein or otherwisederivable from the present disclosure, can be made of any suitableflexible material, for instance a filament, including a cannulatedfilament, a braided filament, and a mono filament. The type, size, andstrength of the flexible material can depend, at least in part, on thetype of anchor with which it is used, any obstructions through which thesuture construct may pass, and the type of procedure in which it isused. In one exemplary embodiment the flexible material is a #2 filament(about 23 gauge to about 24 gauge), such as an Orthocord™ filament thatis commercially available from DePuy Synthes or Ethibond™ filamentavailable from Ethicon, Inc. Generally the filament is relatively thinto minimize any trauma to tissue through which it passes. In someembodiments the filament can have a size between about a #5 filament(about 20 gauge to about 21 gauge) and about a #5-0 filament (about 35gauge to about 38 gauge). The Orthocord™ #2 filament can be usefulbecause it has a braided configuration, which allows other components,including the filament itself, to pass through subcomponents of thebraid without causing damage to the filament. Filaments configured toallow for a cannulated configuration, such as by removing a coretherefrom or having a pre-formed cannulated configuration, can also beused. Orthocord™ suture is approximately fifty-five to sixty-fivepercent PDS™ polydioxanone, which is bioabsorbable, and the remainingthirty-five to forty-five percent ultra-high molecular weightpolyethylene, while Ethibond™ suture is primarily high strengthpolyester. The amount and type of bioabsorbable material, if any,utilized in the filaments of the present disclosure is primarily amatter of surgeon preference for the particular surgical procedure to beperformed. Further, a length of filaments used to form the sutureconstruct 20 can be in the range of about 15 centimeters to about 125centimeters, and in one embodiment it can be about 60 centimeters.

A person having skill in the art will recognize that the configurationsof the present disclosure are just some options for forming sutureconstructs. In the illustrated embodiment the suture construct 20 ismade of a single filament. In other embodiments, however, multiplefilaments can be used, for example by using one filament to create aselectively adjustable loop and another filament to form a fixed eyelet.Further, the type of filament(s) used to form one part of the implantand/or construct does not have to be the same type throughout the entireimplant and/or construct. By way of non-limiting example, the type offilament used to form the construct 20 can be different than the type offilament used for the operative suture 40.

FIGS. 3A-3E illustrate one exemplary method of forming a sutureconstruct 120 having a snare or adjustable loop 122 and a fixed eyelet124. In this exemplary embodiment, the suture construct 120 is shownbeing formed from a single length of suture 130. As shown in FIG. 3A,the length of suture 130 can be folded approximately in half such thatits opposed first and second terminal ends 132 t, 134 t are opposed toeach other, although such symmetry is by no means required. The foldedlength of suture 130 may be referred to as having a first portion, limb,or post, identified herein as limb 132, and a second portion, limb, orpost, identified herein as post 134, with an apex 133 defining alocation at which the limb 132 and post 134 meet. The terms post andlimb are used for convenience purposes to help distinguish a firstportion of the suture 130 from a second portion of the suture 130, andare by no means limiting as to their use, performance, and purpose.

A loop or opening can be formed in a portion of the suture 130. As shownin FIG. 3B, an overhand knot is used form an overhand knot or loop 136that defines an opening 138 approximately on a median location of thelimb 132. Alternatively, other knots, and other locations for the loop136 and opening 138, may be used without departing from the spirit ofthe present disclosure. In embodiments where an anchor is associatedwith the construct 120, such as a soft anchor 180, it can be associatedwith any portion of the suture 130 at any time during the manufacturingprocess. In the illustrated embodiment, the anchor 180 is coupled to thepost 134 along a portion of the post. A person skilled in the art willrecognize many ways by which the post 134 can be associated with theanchor, including, by way of non-limiting example, by threading the post134 through one or more portions of the anchor 180. In otherembodiments, the anchor may be associated with the construct 120 at somelater juncture, including after the construct has been fully formed.

As shown in FIG. 3C, the terminal end 134 t of post 134 can be passedthrough the opening 138 from a first side 120 a of the construct 120 toa second side 120 b of the construct 120. The first side 120 a and thesecond side 120 b can be defined as either side of the opening 138, asshown. In the illustrated embodiment, the terminal end 134 t starts on abottom side of the filament forming the overhand loop 136 (as shown in atop view provided in FIG. 3C, the bottom side being below, orunderneath, the filament forming the overhand loop 136) to a top side ofthe filament forming the overhand loop 136 (as shown in the top viewprovided in FIG. 3C, the top side being above, or on top of, thefilament forming the overhand loop 136) such that as the terminal end134 t enters the opening 138 from the first side 120 a, it passes underthe filament that forms the overhand loop 136, and as the terminal end134 t exits the opening 138 towards the second side 120 b, it passesover the filament that forms the overhand loop 136. Likewise, theterminal end 132 t of the limb 132 also exits the opening 138 such thatit is disposed on the second side 120 b of the construct 120 with itpassing over the filament that forms the overhand loop 136, and theportion of the limb 132 that enters the opening 138 passes under thefilament that forms the overhand loop 136. A person skilled in the artwill recognize that alternative configurations can be used to achieve asimilar configuration in which an opening 138 is formed by an overhandloop 136 (or knots and loops) and terminal ends 132 t, 134 t of a limb132 and post 134 pass through the opening 138 and extend away from theloop 136 in the same direction. As a result of the illustratedconfiguration, the snare, or adjustable loop, 122 is formed on the firstside 120 a of the construct 120. As shown in FIG. 3C, the post 134 isfreely slidable through the opening 138 such that a diameter of snare122 is adjustable as the post 134 is moved with respect to overhand loop136.

As shown in FIG. 3D, the terminal end 132 t of the limb 132 can bethreaded through the opening 138 from the second side 120 b of theconstruct 120 to the first side 120 a of the construct 120 a such that aportion of the limb 132 is disposed within the opening. Moreparticularly, in the illustrated embodiment the terminal end 132 t isthreaded through the opening 138 by passing it from a bottom side of thefilament forming the overhand loop 136 (as shown in a top view providedin FIG. 3D, the bottom side being below, or underneath, the filamentforming the overhand loop 136) to a top side of the filament forming theoverhand loop 136 (as shown in the top view provided in FIG. 3D, the topside being above, or on top of, the filament forming the overhand loop136) such that as the terminal end 132 t enters the opening 138 from thesecond side 120 b, it passes under the filament that forms the overhandloop 136, and as the terminal end 132 t exits the opening 138 towardsthe first side 120 a, it passes over the filament that forms theoverhand loop 136. As a result, a portion of the filament closer to theterminal end 132 t than the terminal end 134 t forms an eyelet 124. Withthe snare 122 and the eyelet 124 both formed by the filament, theopening 138 can be collapsed or dressed to more fully define each of thesnare and eyelet. Collapsing the opening 138 can be achieved in avariety of manners, including but not limited by applying forces to theoverhand loop 136 to collapse it, and/or applying a force in a directionF₁ to the snare 122, and/or applying a force in a direction F₂ to theeyelet 124, as shown in FIG. 3E. The resulting configuration is theconstruct 120 having the snare 122 with the anchor coupled theretodisposed on one side, as shown the first side 120 a, of the dressedoverhand loop 136, and the eyelet 124 disposed on the other side, asshown the second side 120 b, of the dressed overhand loop 136. A size ofthe opening defined by the snare 122 can be adjusted by applying tensionto the terminal end 132 t, and a size of the opening defined by theeyelet 124 can be adjusted by applying tension to the terminal end 134t, although, as discussed below, at least the size of the openingdefined by the eyelet 124 can be selectively locked.

While certain exemplary embodiments are illustrated herein, sutureconstructs 20, 120 can be otherwise configured. For example, while anoverhand knot or loop 136 is shown, the opening 138 can be formed by wayof alternative knots, loops, or other suture or filament formationsknown by those skilled in the art to achieve similar functionality. Onebenefit on an overhand knot 136 is the simplicity and ease ofconstruction, while still providing sufficient strength andadjustability. Moreover, while reference is made to passing certainportions of the limb 132 and the post 134 from the first side 120 a tothe second side 120 b of the construct 120, the limb 132 and the post134 can be passed through the opening 138 in a variety of ways thatresult in a configuration that includes the snare 122 and the eyelet 124disposed on opposite sides of a dressed knot or loop 136.

The suture constructs provided for herein, including but not limited tothe constructs 20, 120, or otherwise derivable from the presentdisclosure, can be operated in a variety of ways. One exemplaryembodiment is illustrated in FIGS. 3F-3K. The anchor 180 is notillustrated in FIGS. 3F-3K to make it easier to follow the proceduresdescribed below. As provided for herein, the anchor 180 can be includedduring the performance of the actions illustrated and described withrespect to FIGS. 3F-3K, the anchor 180 can be added afterward ifdesired, or no anchor at all may be provided for in some instances. Thisis also true for the embodiments described and illustrated with respectto FIGS. 4A-4C.

As shown in FIG. 3F, an operative suture 140 can be threaded through theeyelet 124. Alternatively, the operative suture 140 can be threadedthrough the eyelet at a later step. At this stage the diameter of theeyelet 124 can be varied and is not yet fixed. More particularly, thediameter of the eyelet 124 can be reduced by applying a force on theterminal end 132 t of the limb 132, and the diameter of the eyelet 124can be increased by applying a force on the eyelet 124. As shown betweenFIGS. 3F and 3G, a force in a direction F₃ is applied to the terminalend 132 t (FIG. 3F) to reduce the diameter of the eyelet 124 (FIG. 3G).While a person skilled in the art, in view of the present disclosures,will recognize a variety of diameter sizes that can be used inconjunction with the eyelet 124, in some embodiments the diameter of theeyelet 124 can be reduced to a diameter approximately in the range ofabout 1.5 millimeters to about 15 millimeters, and in some embodimentsthe diameter can be about 3 millimeters. A variety of factors canincludes the size of the diameter of the eyelet 124, including but notlimited to the type of procedure being formed, the length and thicknessof the filament being used to form the construct 120 and/or theoperative suture 140, the type of tissue with which the construct isbeing used, the amount of tension that will be applied by the operativesuture 140 to the eyelet 124 in subsequent use, and/or whether anyresistance is desired between the operative suture 140 and the eyelet124 (as opposed to allowing the operative suture 140 to easily slidewith respect to the eyelet 124). Generally the diameter of the eyelet124 should be kept small so that the implant is not too large, but notso small so as to hinder the ability to use the operative suture 140and/or lock the eyelet 124—the locking of the eyelet 124 being discussedfurther below.

As demonstrated by the illustrations in FIGS. 3H and 3I, one benefit ofthe construct formation that includes the eyelet 124 as provided is thatthe diameter of the eyelet 124, while adjustable as described above, canbe locked or fixed independent of any fixation of a size of theadjustable loop or snare 122. Turning to FIG. 3H, a first half-hitchknot 150 a can be formed (shown in an uncinched configuration) bywrapping the terminal end 132 t of the limb 132 around lengths of twoportions or limbs 122 a, 122 b of the snare 122, such portions beingproximate to the overhand knot 136. The two limbs 122 a, 122 b of thesnare 122 can function as a post that runs through the first half-hitchknot 150 a such that they can both freely slide therethrough. A personskilled in the art will recognize a variety of different knots typesthat can be used to form the first half-hitch knot 150 a, including butnot limited to a binding knot, such as a granny knot. A plurality ofgranny knots can be formed, for example three, to help keep thisillustrated configuration intact, such as by helping to keep the post ina substantially straight configuration. Alternatively, the half-hitchknot 150 a, and/or additional half-hitch knots, can be formed around oneof the two limbs 122 a, 122 b only.

As shown in FIG. 3I, three half-hitch knots 150 a, 150 b, and 150 c areformed around the two limbs 122 a, 122 b to fix the diameter of theeyelet 124. In this figure, the first half-hitch 150 a is now cinched,with the two additional half-hitch knots 150 b and 150 c being formed ontop of the first half-hitch knot 150 a. The post 134 can be slidablethrough the half-hitch knots 150 a, 150 b, and 150 c, and slidablethrough the overhand knot 136, such that a diameter of the snare 122 canstill be adjusted while the diameter of the eyelet 124 remains fixed. Aperson skilled in the art, in view of the present disclosures, willrecognize the advantageous configuration that results from having asuture construct 120 with a fixed diameter eyelet 124 (and/orselectively fixable as provided for herein) and a variable diametersnare 122.

The suture construct 120 can further include an actuable lockingfeature, or locking knot 160 (FIG. 3K), which can be used to fix thediameter of the snare 122. This can allow a user to fix the size of thesnare 122 upon completion of a procedure to prevent the construct 120from moving from a desired fixed location and/or from unintentionallymoving and/or releasing the soft anchor 180. As described andillustrated below, the operative suture 140 is used to aid in formingthe locking knot 160, with the fixed eyelet 124 serving as a limb andthe post 134 serving as a post.

As shown in FIG. 3J, the operative suture 140 can be loosely tied aroundthe post 134, for instance as a half-hitch knot 142, distal to theoverhand knot 136. In forming the half-hitch knot 142, the operativesuture 140 can be passed from a bottom side of the post 134 (as shown ina top view provided in FIG. 3J, the bottom side being below, orunderneath, the post 134) and up over a top side of the post 134 (asshown in the top view provided in FIG. 3J, the top side being above, oron top of, the post 134) before passing below itself to complete theknot 142. The half-hitch knot 142 can be tightened, i.e., a size of anopening 143 formed by the knot 142 can be collapsed, by applying a forcein a direction F₄ to the operative suture 140, as shown in FIG. 3J. As aresult, a proximal portion 140 p of the operative suture 140 that islooped through or otherwise disposed in the eyelet 124, pulls the eyelet124 around the post 134, thereby forming the locking knot 160.

One advantage of the operative suture 140 being threaded through thefixed eyelet 124 is the operative suture 140 can be used to aid in theformation of the locking knot 160 with the fixed eyelet. Alternatively,a person skilled in the art will recognize the locking knot 160 can beformed without using the operative suture 140, for instance by manuallymanipulating the fixed eyelet 124 and/or using other tools or filamentsto manipulate the location of the eyelet 124 with respect to the post134 in view of the present disclosures.

As shown in FIG. 3K, the locking knot 160 is a half-hitch knot that isdirectly proximate to the overhand knot 136. Alternatively, the lockingknot 160 can be formed a distance away from the overhand knot 136. Asalso shown in FIG. 3K, the overhand knot 136 is directly intermediatethe locking knot 160 on the second side 120 b of the construct 120 andthe three half-hitch knots 150 a, 150, and 150 c on the first side 120 aof the construct 120. In the illustrated embodiment, the post 134 isstill slidable through the three half-hitch knots 150 a, 150 b, 150 c,the overhand knot 136, and the locking knot 160 such that the size ofthe snare 122 can still be adjusted because the locking knot 160 isstill in a first, unlocked configuration. Details about how the size ofthe snare 122 can be adjusted by the post 134, as well as details abouthow to move the locking knot 160 to the second, locked configuration,are provided with respect to FIGS. 4A-4C.

FIG. 4A illustrates the configuration of the construct 120 as it isshown in FIG. 3K, with the post 134 being in a substantially straightline through the knots 150 a, 150 b, 150 c, 136, and 160. As shown, aforce in a direction F_(T) can be applied to the post 134 to slide thepost within the locking knot 160 to reduce the diameter of the snare122, as shown in FIG. 4B. In some embodiments the force in the directionF_(T) can be approximately in the range of about 5 Newtons to about 150Newtons, and in some embodiments the force in the direction F_(T) can beabout 20 Newtons. The resulting diameter of the snare 122 can be justabout any size known to those skilled in the art, and can depend, atleast in part, on the size and shape of other devices, ligaments,implantable bodies, soft anchors, and the like with which the construct120 is being used, the type of procedure being performed, anatomicalconditions, and the preferences of the user. In some surgicalembodiments, a diameter of the snare 122 can be adjusted to sizes aslarge as about 50 centimeters to sizes as small as about 1 millimeter.

When the diameter of the snare 122 is at the desired size, the lockingknot 160 can be actuated from the unlocked configuration (illustrated,for example, in FIG. 4A) to the locked configuration (illustrated, forexample, in FIG. 4C). As shown, the locking knot or eyelet 160 isflipped, thus causing it to lock and prevent the post 134 from easilysliding with respect to it. More particularly, as shown in FIG. 4B, aforce in a direction F_(L) can be applied to the operative suture 140,which is disposed through the locking knot 160, to cause the lockingknot 160 to flip. By flipping the locking knot 160, it causes the post134 to be in a relatively tortuous path within the locking knot 160(i.e., it is no longer in a substantially straight line through the knot160, or the other knots 150 a, 150 b, 150 c, and 136), placing thelocking knot 160 in the second, locked configuration with the diameterof the snare 122 being substantially fixed. Optionally, one or moreadditional half-hitches can be formed at the locking knot 160 to furthersecure the diameter of the snare 122.

When the construct 120 is in a locked configuration, a location of atendon coupled to or otherwise associated with the snare 122 can befixed at a desired location. Accordingly, during a surgical procedure,placing the construct 120 in the locked configuration can set thedesired location of the tendon with respect to the anatomy of thesubject. When the construct 120 is in the locked configuration, it canalso prevent actuation of a soft anchor coupled thereto because in thelocked configuration a size of a diameter of the construct 120 cannotgenerally be adjusted. A person skilled in the art, in view of thepresent disclosure, will recognize other configurations and actions thatcan be performed when the construct 120 is in a locked configuration.Likewise, a number of configurations and actions can be performed whenthe construct 120 is in an unlocked configuration. In suchconfigurations, a soft suture anchor can be deployed, and/or a locationof a tendon can be adjusted by changing a size of the diameter of theconstruct 120, among other actions that can be performed.

One benefit of the presently designed construct 120 is that it can bemoved back from the locked configuration to an unlocked configuration.As shown in FIG. 4C, an unlocking force in a direction F_(UL) can beapplied to the post 134 while the remainder of the construct 120 issecurely held to flip the locking knot 160 back into the unlockedconfiguration. Alternatively, or additionally, the operative suture 140can be used to flip the locking knot 160 back into the unlockedconfiguration. The ability to selectively lock and unlock the sutureconstruct 120 can provide a number of benefits. For example, it allows auser to selectively and incrementally set and adjust the diameter of thesnare 122. Thus, if a user is performing a procedure in which it wouldbe advantageous for the snare 122 diameter to be locked in for oneperiod of time at one diameter but locked in for another period oftime(s) at another diameter(s), the present construct would allow thelocking knot 160 to be toggled between the unlocked and lockedconfigurations to achieve this flexibility. Further, the lock-unlockcapability of the construct 120 allows for errors to be corrected. Forexample, if the diameter of the snare 122 was set at the wrong size, thelocking knot 160 can be moved to the unlocked configuration to fix thesnare diameter to the desired size. Likewise, if the size of the snarediameter adjusts during use, for instance because there is some slippageor the filament becomes strained and stretches, the locking knot 160 canbe moved to the unlocked configuration to fix the snare diameter to thedesired size. Once the locking knot 160 is in the unlockedconfiguration, the post 134 is able to slide within the locking knot 160to adjust the diameter of the snare 122.

Advantageously, as the operative suture 140 is slidably disposed withinthe eyelet 124, and not through a portion of a soft anchor, or otherimplantable body, the operative suture 140 can be removed afterimplantation of the suture construct 120. A further advantage of theoperative suture 140 being slidably disposed within the eyelet 124 isthat the operative suture can be freely adjusted relative to the sutureconstruct 120 to permit the operative suture 140 to be used for otheraspect of the procedure, or for additional repairs. These benefits arerealized in contrast to suture constructs where implantable bodies, oranchors, are threaded onto the operative suture itself.

A person skilled in the art will recognize that the disclosures providedfor with respect to FIGS. 3A-3K can be performed prior to delivering theconstruct 120 to a surgical procedure room, which is to say they canrepresent a method of manufacturing a construct for use in a surgicalprocedure. Alternatively, one or more of the steps can be performedon-site as part of a surgical procedure. Similarly, the disclosuresprovided for with respect to FIGS. 4A-4C can often be performed on-siteas part of a surgical procedure, although, in some instances, at leastsome aspects can be performed in advance of delivery to the surgicalprocedure room. For example, in some embodiments the construct 120 canbe delivered in a locked configuration with the operative suture 140already associated with the construct 120 and/or the terminal end 132 ttrimmed away. The construct 120 can still be selectively unlocked insuch an instance, thus achieving the types of benefits provided for bythe present disclosures.

While methods of using the suture constructs, or aspects thereof, areprovided for above (e.g., the constructs 20, 120), one, more explicit,but non-limiting, exemplary method of using a suture construct implantis provided for with reference back to FIG. 2. A person skilled in theart will recognize such methods can likewise be applicable to otherconstructs illustrated herein or otherwise derivable from the presentdisclosure.

As shown, the implant 10 can include the suture construct 20 and a softanchor 80. The soft anchor 80 can be threaded onto the snare 22, asshown in FIG. 1. Further, the implant 10 can be associated with softtissue 92 to be attached to bone 94. In the illustrated embodiment, someportion of the construct 20 is passed through the tissue 92, althoughother techniques for associating an implant 10 with a soft tissue 92 canbe used without departing from the spirit of the present disclosure(e.g., wrapping the implant 10 around the tissue 92).

A bore 90 can be formed in a bone 94 using any technique known to thoseskilled in the art. The implant 10 can then be disposed in the bore 90so that the implant can be positioned to draw the tissue 92 towards thebone 94 to achieve the repair. As shown, because the anchor 80 is soft,it can be actuated into the anchoring configuration, as shown in FIG. 2.In the illustrated embodiment, the actuation is initiated by reducingthe diameter of the snare 22 via application of a force in the directionF to the post 34 (FIG. 1), although a person skilled in the art willrecognize a variety of ways by which the soft anchor 80 can be actuatedinto the anchoring configuration. Likewise, a person skilled in the artwill also appreciate that other types of anchors may result in otherways by which the anchor, construct, bone, and tissue are associated. Byway of non-limiting example, if the anchor is a hard anchor rather thana soft anchor, the anchor can be implanted in a pre-formed bore or theanchor can be impacted into the bone without a pre-formed bore. The typeof anchor, and how the anchor is associated with any of the bone,tissue, or construct, are by no means limiting with respect to thepresent disclosure. Generally, anchors provided for in conjunction withthe present disclosures engage and/or impinge walls of the bore 90,penetrating cancellous bone in some embodiments, and/or are formed suchthat in their deployed configuration they cannot easily pass out of abore (e.g., the bore 90) in which they are disposed so that the anchorcan be substantially fixed with respect to the bone 94.

As shown in FIG. 2, after the anchor 80 is deployed, a force in adirection F_(L) can be applied to the operative suture 40, and thus thefixed eyelet 24, to selectively actuate a locking knot 60 according tomethods disclosed herein. Knot 60, as shown in FIGS. 1 and 2, caninclude knots 150 a, 150 b, 150 c, 136, and 160, as shown in FIGS.3A-4C, among others provided for herein or otherwise derivabletherefrom. By way of non-limiting example, the locking knot 60 can beactuated between the unlocked and unlocked configurations in a mannerakin to those provided for with respect to the locking knot 160 inconjunction with FIGS. 4A-4C.

Upon completion of a procedure, with the suture construct 10, as well asits components (e.g., the snare 22), fixed at its desired location, asshown in FIG. 2, the operative suture 40 can be removed from the fixedeyelet 24 by sliding it through and out of the fixed eyelet. Further,portions of the post 34 and other excess portions of filament can betrimmed to remove unnecessary filament that may get in the way, causedamage to tissue, etc. Alternatively, either or both the operativesuture 40 and the post 34 can remain in place and be used to completeadditional actions, such as facilitating capsular repair.

A number of alternative configurations are possible in view of thepresent disclosures. Some non-limiting examples are provided for inFIGS. 5A, 5B, 6A, 6B, 8A, and 8B.

FIG. 5A provides for an implant 210 that includes a suture construct 220that is substantially similar to the suture construct 120 discussedabove. For example, as shown, the suture construct 220 includes anadjustable snare loop 222, a fixed eyelet 224, a knot or loop 236, and apost 234, among other features illustrated or otherwise known to beincluded in view of the present disclosures and knowledge of thoseskilled in the art. For example, the loop 136 can also be associatedwith one or more half-hitch knots (akin to knots 150 a, 150 b, and 150c) and/or a locking knot (akin to knot 160). The post 234 can be used toreduce the diameter of the snare loop 222, as described above withreference to the suture construct 120. An operative suture 240 can bedisposed or otherwise associated with the fixed eyelet 224, and can beused or operated in manners provided for herein, such as to selectivelylock and unlock movement of the adjustable snare loop 222 via the loop236 and associated features (e.g., knots).

Just as the implant 110 also included additional components, such as theanchor 80, the implant 210 can also include additional components, suchas implantable bodies 212 and 214, also referred to as cortical buttons.The implantable bodies 212 and 214 illustrated in FIG. 5A, as with thoseillustrated in subsequent figures, are generally schematic in nature. Aperson skilled in the art will recognize many different sizes, shapes,and configurations of cortical buttons. A body of a cortical button canbe generally described as a somewhat rectangular, elongate shape withcurved leading and trailing terminal ends 212 e, 212 f and 214 e, 214 f(curves not illustrated in this schematic illustration, but understoodby a person skilled in the art as one design option). One or morethrough-holes 212 a and 214 a, 214 b can be formed in the bodies 212 and214. In the illustrated embodiment, the implantable body 212 includesone through-hole 212 a that is approximately centrally disposed along alength of the body 212, while the implantable body 214 includes twothrough-holes 214 a, 214 b that are approximately equally spaced along alength of the body from a center of the body 214. Diameters of thethrough-holes 212 a, 214 a, 214 b can be the same or different on eitheror both of the bodies 212, 214. A thickness of each of the bodies 212,214 can be defined by the distance between a proximal surface 212 p and214 p and a distal surface 212 d and 214 d of the respective bodies, anda width (not visible in FIG. 5A) can be defined by a distance betweenthe two sidewalls disposed on a same side of a length of the respectivebodies 212, 214.

The suture construct 220 can be associated with the implantable bodies212 and 214 by passing or otherwise disposing portions thereof throughthe through-holes 212 a and 214 a, 214 b. More particularly, as shown,the loop 222 can be thread or otherwise passed or disposed through thethrough-hole 212 a between the proximal side 212 p of the first (asshown upper) body 212 and the distal side 212 d of the body 212. Thediameter of the through-hole 212 a can be less than a diameter of theresulting knot 236 such that the knot 236 is maintained on the proximalside 212 p of the upper body 212, thus forming an interference fitbetween the knot 236 and body 212. The loop 222 can likewise be threador otherwise passed or disposed through the through-holes 214 a, 214 b.More particularly, as shown, a distal end 222 d of the loop 222 can bethread through the through-holes 214 a, 214 b between the proximal side214 p of the second (as shown lower) body 214 and the distal side 214 dof the body 214.

A person skilled in the art, in view of the present disclosures, willunderstand that the procedure for associating the bodies 212, 214 withthe construct 220 can be performed in a variety of different manners,such as by threading the bodies 212, 214 onto the construct 220 prior toforming the loop 236, prior to dressing the loop 236, etc. This islikewise true for the other combinations of constructs (e.g., constructs220′, 220″, 220′″, 320, 320′) and bodies (212′, 214′, 212″, 214″, 212′″,214′″, 312, 314, 312′, 314′) provided for herein, or combinations thatcan be derived in view of the present disclosures. The suture constructimplant 210 can be used in any of the variety of procedures as describedbelow with regards to alternative suture construct implants 210′, 210″,210′″310, and 310′, as well as other procedures known or otherwisederivable in view of the present disclosures. Likewise, the otherimplants provided for herein (e.g., implants 210′, 210″, 210′″, 310, and310′) can be used in any of the variety of procedures described herein,as well as other procedures known or otherwise derivable in view of thepresent disclosures.

FIG. 5B provides for an alternative configuration of an implant 210′that allows a knot 236′, as well as a fixed eyelet 224′, to be disposedunderneath an implantable body 212′, as shown between the implantablebodies 212′ and 214′. The configuration and operability of a sutureconstruct 220′, adjustable snare loop 222′, fixed eyelet 224′, knot orloop 236′, and post 234′ are generally akin to their counterpartcomponents of the implant 210 of FIG. 5A. Likewise, the configurationand operability of implantable bodies 212′ and 214′ are also generallyakin to their counterpart implantable bodies 212 and 214, except, forexample, that the first (as shown upper) implantable body 212′ includestwo through-holes 212 a′, 212 b′ instead of one through-hole 212 a. Thesecond (as shown lower) implantable body 214′ includes two through-holes214 a′, 214 b′, just like the implantable body 214.

The suture construct 220′ can be associated with the implantable bodies212′ and 214′ by passing or otherwise disposing portions thereof throughthe through-holes 212 a′, 212 b′ and 214 a′, 214 b′. The illustratedconfiguration is similar to that of the implant 210 of FIG. 5A in that adistal end 222 d′ of the loop 222′ can be thread through thethrough-holes 214 a′, 214 b′ between a proximal side 214 p′ of thesecond body 214′ and a distal side 214 d′ of the second body 214′. Theadditional through-hole 212 b′ in the first implantable body 212′ canallow a proximal end 222 p′ of the loop 222′ to be thread or otherwisepassed or disposed through both through-holes 212 a′, 212 b′ between theproximal side 212 p′ of the first body 212′ and the distal side 212 d′of the first body 212′. As shown, any or all of a terminal end 222 t′ ofthe loop 222′ proximate to the knot 236′, the knot 236′, and the eyelet224′ can be disposed distal of the distal side 212 d′ of the first body212′. In the illustrated embodiment, the terminal end 222 t′ of the loop222′, the knot 236′, and the eyelet 224′ are all disposed distal of thedistal side 212 d′ of the first body 212′ and proximal of the proximalside 214 p′ of the second body 214′. In some instances, at least aportion of the terminal end 222 t′ of the loop 222′ may be disposedwithin the through-hole through which the loop 222′ is passed and/orproximal of that through-hole. Disposing some or all of these portionsbelow the distal side 212 d′ of the first body 212′ can help preventdamage to tissue (e.g., inflammation, irritation) that can be caused bythose portions contacting the tissue when those portions are disposedproximal of the proximal side 212 p′ of the first body 212′. Theillustrated configuration can also help keep such portions intact, suchas by preventing accidental cutting of the knot 236′ when trimmingsuture tails, such as the post 234′. As shown, the post 234′ and/or anoperative suture 240′ associated with the eyelet 224′ can extend throughthe through-hole 214 b′, although other configurations are possible,including but not limited to having one or both of them pass through anyof the through-holes 212 a′, 212 b′, 214 a′, 214 b′, and/or having oneor both of them not extend through any of the through-holes 212 a′, 212b′, 214 a′, 214 b′. Another alternative implant 210″ is shown in FIG. 6.The implant 210″ includes a suture construct 220″, which can besubstantially similar to the suture constructs 120, 220 discussed above.For example, as shown, the suture construct 220″ include an adjustablesnare loop 222″, a fixed eyelet 224″, a knot or loop 236″, and a post234″, among other features illustrated or otherwise known to be includedin view of the present disclosures and knowledge of those skilled in theart. For example, the loop 236″ can also be associated with one or morehalf-hitch knots (akin to knots 150 a, 150 b, and 150 c) and/or alocking knot (akin to knot 160). The post 234″ can be used to reduce thediameter of the snare loop 222″, as described above with reference tothe suture construct 120. An operative suture 240″ can be disposed orotherwise associated with the fixed eyelet 224″, and can be used oroperated in manners provided for herein, such as to selectively lock andunlock movement of the adjustable snare loop 222″ via the loop 236″ andassociated features (e.g., knots).

Similar to the implants 110, 210, and 210′, the implant 210″ can includeadditional components, such as implantable bodies 212″ and 214″, againalternately referred to as cortical buttons. The implantable bodies 212″and 214″ illustrated in FIG. 6 are schematic in nature. A person skilledin the art will recognize various sizes, shapes, and configurations thatcan be used as the implantable bodies 212″ and 214″. Similar to theimplantable body 212, the first (as shown upper) implantable body 212″includes a through-hole 212 a″ that is approximately centrally disposedalong a length of the body 212″. Differing from the illustratedimplantable bodies 214, 214′, the second (as shown lower) implantablebody 214″ includes just one through-hole, a through-hole 214 a″, thethrough-hole being approximately centrally disposed along a length ofthe body 214″. Diameters of the through-holes 212 a″, 214 a″ can be thesame or different on either or both of the bodies 212″, 214″. The bodies212″, 214″ can also have thicknesses and widths, as described above withrespect to the bodies 212, 214. And locations of the through-holes 212a″, 214 a″ can be varied, such as one or both not being approximatelycentrally disposed along a length of their respective bodies 212″, 214″.

The suture construct 220″ can be associated with the implantable bodies212″ and 214″ by passing or otherwise disposing portions thereof throughthe through-holes 212 a″ and 214 a″. More particularly, as shown, theloop 222″ can be thread or otherwise passed or disposed through thethrough-hole 212 a″ between a proximal side 212 p″ of the first body212″ and a distal side 212 d″ of the body 212″. The diameter of thethrough-hole 212 a″ can be less than a diameter of the resulting knot236″ such that the knot 236″ is maintained on the proximal side 212″ ofthe upper body 212″, thus forming an interference fit between the knot236″ and body 212″. While in the embodiment illustrated in FIG. 5A theloop 222 was likewise disposed through the body 214 via one or morethrough-holes (e.g., the through-holes 214 a and 214 b), for the implant210″ the loop 222″ is coupled to or otherwise associated with the lowerbody 214″ by way of an attachment suture 241″. More particularly, asshown, the attachment suture 241″ is coupled to a distal end 222 d″ ofthe loop 222″, for instance by passing a portion of the attachmentsuture 241″ through a portion of the loop 222″, and the attaching sutureis thread or otherwise passed or disposed through the through-hole 214a″ between a proximal side 214 p″ and a distal side 214 d″ of the body214″. A knot 242″ disposed on the attachment suture 241″, as shown onits distal end 240 d″, although other locations are possible, can have adiameter that is larger than a diameter of the through-hole 214 a″ suchthat the knot 242″ is maintained on the distal side 214 d″ of the body214″, thus forming an interference fit between the knot 242″ and body214″. As a result, a location of the loop 222″ is maintained withrespect to the body 214 d″ when a force in an upward direction, i.e.,towards the upper body 212″, is applied to a portion of the implant210″. Similar to the implants 110, 210, and 210′, the implant 210″ canbe used in any variety of procedures as described below, as well asother procedures known or otherwise derivable in view of the presentdisclosures.

FIG. 6B provides for an alternative configuration of an implant 210″that combines some of the benefits described with respect to the implant210′ of FIG. 5B with some of the benefits described with respect to theimplant 210″ of FIG. 6A. The configuration and operability of a sutureconstruct 220′″, adjustable snare loop 222′″, fixed eyelet 224′″, knotor loop 236′″, post 234′″, attachment suture 241′″, and knot 242′″ aregenerally akin to their counterpart components of the implants 210,210′, and 210″ of FIGS. 5A, 5B, and 6A, respectively. Further, theconfiguration and operability of implantable bodies 212′″ and 214′″ aregenerally akin to their counterpart implantable bodies 212′ and 214,214′, with the both the first (as shown upper) implantable body and thesecond (as shown lower) implantable body each having two through-holes212 a′″, 212 b′″ and 214 a′″, 214 b′″, respectively.

The suture construct 220′″ can be associated with the implantable bodies212′″ and 214′″ by passing or otherwise disposing portions thereofthrough the through-holes 212 a′″, 212 b′″, 214 a′″, 214 b′″. Theillustrated configuration of FIG. 6B with respect to the firstimplantable body 212′″ is similar to that of the implant 210′ of FIG. 5Bin that a terminal end 222 t′″ of the loop 222′″, the knot 236′″, andthe eyelet 224′″ can all be disposed distal of a distal side 212 d′″ ofthe first body 212′″. Likewise, the illustrated configuration of FIG. 6Bwith respect to the second implantable body 214′″ is similar to that ofthe implant 210′ of FIG. 5B in that the terminal end 222 t′″ of the loop222′″, the knot 236′″, and the eyelet 224′″ can all be disposed proximalof a proximal side 214 p′″ of the second body 214′″, and further, theoperative suture 240′″ and the post 234′″ can extend through thethrough-hole 214 b′″. A further benefit illustrated with respect to theimplant 210′″ of FIG. 6B is that the attachment suture 240′″ can bepassed through the through-hole 214 a′″ such that the knot 242″ isdisposed proximal of the proximal side 214 p′″ of the second body. Thislocation can be beneficial for the same reasons described above as towhy disposing the knot 236′ and eyelet 224′ distal of the distal side212 d′ of the implantable body 212′ is beneficial with respect to theimplant 210′ of FIG. 5B. As shown, in the illustrated embodiment, theknot 242′″ can be disposed distal of the distal side 212 d′″ of theimplantable body 212′″.

FIG. 7 provides for one non-limiting example of a surgical procedurethat can be performed using the implant 210′. A person skilled in theart, in view of the present disclosures, will understand variations ofthe described procedure, as well as other procedures, that can beperformed using the implant 210′. Likewise, a person skilled in the art,in view of the present disclosures, will understand other implants,including but not limited to the implants described herein or otherwisederivable from the present disclosures, and/or variations thereof, thatcan be used in conjunction with procedure described with respect to FIG.7.

FIG. 7 is illustrative of a meniscal tear 292′ involving tissue 290 a′and 290 b′. The tissue 290 a′, 290 b′ can be prepared according toaccepted surgical techniques and the implant 210′ can be introduced tothe surgical site. In the illustrated embodiment, the implant 210′ issituated such that the lower cortical button 214′ is disposed proximateto the tissue 290 b′, with its proximal side 214 p′ disposed against thetissue 290 b′, the upper cortical button 212′ is disposed proximate tothe tissue 290 a′, with its distal side 212 d′ disposed against thetissue 290 a′, and the suture construct 220′ passing between thecortical buttons 212′, 214′ such that it passes through portions of thetissue 290 a′, across the tear 292′, and through portions of the tissue290 b′. A person skilled in the art will recognize many differenttechniques that can be performed to achieve this configuration,including but not limited to passing one or both cortical buttons 212′,214′ through portions of the tissue 290 a′, 290 b′ and/or first passingthe construct 220′ through the tissue 290 a′, 290 b′ and thenassociating the buttons 212′, 214′ with the tissue 290 a′, 290 b′ so asnot to pass any buttons through the tissue. Likewise, although theconstruct 220′ is shown passing through portions of the tissue 290 a′,290 b′, in other configurations the construct 220′ can be wrappedaround, or be otherwise associated with the tissue 290 a′, 290 b′, inlieu of or in addition to passing the construct 220′ through the tissue290 a′, 290 b′. The key to this set-up is that the implant 210′ isassociated with both tissues 290 a′ and 290 b′ such that the construct220′ can be operable to draw the tissues together.

Once the implant 210′ is associated with the tissue 290 a′, 290 b′, theimplant 210′ can be operated to draw the tissue 290 a′, 290 b′ together,thereby closing the tear 292′. This can be accomplished, for example, byapplying a force in a direction F_(t) on the post 234′ to reduce thediameter of the snare 222′. The surgeon can hold the knot 236′, and/orthe upper cortical button 212′, in place during the tightening of thesnare 222′ to provide a counter force to the force in the directionF_(t) to prevent the implant 210′ from being pulled out of the tissue.The counter force can be applied, for example, by a knot pusher (notshown), or by other tools and/or techniques known to those skilled inthe art, e.g., applying the counter force by hand if access at thesurgical site exists. Once the tissue 290 a′, 290 b′ is brought intocontact to close the tear 292′, the implant 210′ can be actuated to fixthe diameter of the snare 222′. As discussed above with respect to theimplant 110, the implant 210′ can be locked by the application of alocking force in a direction F_(L) to an operative suture 240′, which isdisposed in the eyelet 224′ of the implant 210′. By applying the lockingforce in the direction F_(L) to the operative suture, the locking knot,which is part of the knot 236′, is actuated and thereby changes the pathof the post 234′ from a straight path through the knot 236′ to atortuous path. While the post 234′ is in the tortuous path through theknot 236′, the diameter of the snare 222′ is substantially fixed,thereby retaining the tissue 290 a′, 290 b′ together to allow for thetear 292′ to heal according to accepted medical techniques. Once thesnare 222′ of the implant 210′ has been fixed, the operative suture 240′can be removed from the eyelet 224′ and the post 234′ can be trimmed.Alternatively, the operative suture 240′ and the post 234′ can remain toaid in additional repairs, such as facilitating capsular repair.

Yet another alternative implant 310 is illustrated in FIGS. 8A and 9.The implant 310 includes a suture construct 320 and implantable body orcortical button 312, which can be substantially similar to the sutureconstructs 120, 220, 220′ and the implantable bodies 212, 212′, and 214′discussed above. Other configurations of suture constructs andimplantable bodies, including other configurations described above orotherwise derivable in view of the present disclosures, can also beused. In the illustrated embodiment, the suture construct 320 includesan adjustable snare loop 322, a fixed eyelet 324, a knot or loop 336,and a post 334, among other features illustrated or otherwise known tobe included in view of the present disclosures and knowledge skilled inthe art. For example, the loop 336 can also be associated with one ormore half-hitch knots (akin to knots 150 a, 150 b, and 150 c) and/or alocking knot (akin to knot 160). The post 334 can be used to reduce thediameter of the snare loop 322, as described above with reference to thesuture construct 120. An operative suture 340 can be disposed orotherwise associated with the fixed eyelet 324, and can be used oroperated in manners provided for herein, such as to selectively lock andunlock movement of the adjustable snare loop 322 via the loop 336 andassociated features (e.g., knots).

Further, similar to the implants 110, 210, and 210′, the implantablebody 312 is schematically illustrated, and a person skilled in the artwill recognize various sizes, shapes, and configurations that can beused as the implantable body 312. In the illustrated embodiment, theimplantable body 312 includes a through-hole 312 a that is approximatelycentrally disposed along a length of the body 312, the hole 312 aextending between a proximal side 312 p and a distal side 312 d of thebody 312. The suture construct 320 can be coupled to or otherwiseassociated with the implantable body 312 using techniques provided forherein or otherwise known to those skilled in the art. As shown, aproximal end 322 p of the snare loop 322 is disposed proximate to theknot 336 and the implantable body 312, with the knot 336 being disposedat or proximal of the proximal side 312 p with a major diameter of theknot 336 being greater than a diameter of the through-hole 312 a so thata location of the construct 320 with respect to the implantable body 312can be maintained.

A tendon 396 can be associated with the adjustable snare loop 322, asshown at a distal end 322 d of the snare loop 322. The tendon 396 can becoupled to or otherwise associated with the adjustable snare loop 322using any techniques known to those skilled in the art, including butnot limited to passing the tendon 396 through an opening defined by thesnare such that a portion of the tendon 396 is disposed on the distalend 322 of the loop 322, with other portions of the tendon 396 extendingon either side of the loop 322 as shown. In alternative, non-limitingembodiments, a portion of the snare loop 322 can be thread through aportion of the tendon 396 and the loop 322 can be manipulated such thatit wraps around a portion of the tendon 396. In the illustratedembodiment, the tendon 396 can be freely slidable with respect to theloop 322, although in other embodiments it can be fixed relative to thesnare loop 332.

FIG. 8B provides for an alternative configuration of an implant 310′that, similar to the implants 210′ and 210′″, allows a knot 336′, aswell as a fixed eyelet 324′, to be disposed underneath an implantablebody 312′. The configuration and operability of a suture construct 320′,adjustable snare loop 322′, fixed eyelet 324′, knot or loop 336′, andpost 334′ are generally akin to their counterpart components of theimplant 310 of FIG. 8A, and thus their counterpart components of theimplants 210, 210′, 210″, and 210′″. Likewise, the configuration andoperability of implantable body 312′ is generally akin to itscounterpart implantable bodies 212′ and 212′″, with the implantable body312′ having two through-holes 312 a′, 312 b′.

The suture construct 320′ can be associated with the implantable body312′ in similar ways as described above, with one resultingconfiguration being one in which a terminal end 322 t′ of the loop 322′,the knot 336′, and the eyelet 324′ being disposed distal of a distalside 312 d′ of the implantable body 312′. AS discussed above withrespect to the loop 222′, in some instances, at least a portion of theterminal end 322 t′ of the loop 322′ may be disposed within thethrough-hole through which the loop 322′ is passed and/or proximal ofthat through-hole. As shown, an operative suture 340′ and the post 334′can likewise be disposed distal of the distal side 312 d′ of theimplantable body 312′, such sutures extending distally therefrom. Theconfiguration of the suture construct 320′ having the knot 336′ and theeyelet 324′ disposed distal of the distal side 312 d′ of the implantablebody 312′, i.e., underneath the body 312′, allows sutures to betensioned in a way that causes the implant 310′ to operate in apulley-like manner. This “pulley” movement can cause the repair tobecome taut as tension continues to be applied to the implant 310′, forexample by applying tension to the post 334′. This is true at least forthe other configurations provided above in which a knot and eyelet aredisposed distal of a distal side of an implantable body, such as for theimplants 210′ and 210′″ of FIGS. 5B and 6B, respectively. Still further,in embodiments that include multiple implantable bodies, such as theimplants 210′ and 210′″ of FIGS. 5B and 6B, respectively, tension canalso be derived between the plurality of implantable bodies. Further,similar to the description above with respect to the implant 310, atendon 396′ can be associated with the adjustable snare loop 322′, asshown at a distal end 322 d′ of the snare loop 322′. The tendon 396′ canbe coupled to or otherwise associated with the adjustable snare loop322′ using any techniques known to those skilled in the art, includingbut not limited to those provided above.

FIG. 9 provides one exemplary embodiment of the implant 310 being usedin a surgical repair procedure that includes a bone 390 and graft 396.Many different types of surgical procedures can be performed using theimplant 310, but in some exemplary embodiments it can be an ACL repair.The repair can be prepared according to accepted surgical techniques,such as forming a bone bore 380 in the bone 390, the bore 380 being aspace into which the graft 396 is implanted.

The implant 310 can be passed through the bore 380 until the implantablebody 312 is located above a proximal surface 390 p of the bone 390. Aperson skilled in the art will recognize a number of ways by which theimplant 310 can be advanced through the bore 380, but in one embodimenta force in a direction F_(B) can be applied to the operative suture 340to advance the implant 310, and thus the graft 396, in a similardirection, up through the bore 380. In such instances, the eyelet 324can have been manipulated into a locked configuration so thatapplication of the force in the direction F_(B) to the operative suture340 does not accidentally cause a diameter of the eyelet 324 and/or thesuture loop 322 to change. Alternatively, the eyelet 324 can remain inthe unlocked configuration, as application of force to the operativesuture 340 does not necessarily cause a diameter of the eyelet 324and/or suture loop 322 to change. Further, in some instances, it may bedesirable to both advance the implant 310 through the bore 380 whilealso, simultaneously, adjusting a length of the suture loop 322, forinstance by applying a force in a direction F_(t) to the post 334.

After the body 312 has passed through the bore 380, proximal of theproximal surface 390 p of the bone, the body 312 can be manipulated suchthat one of its surfaces, e.g., the proximal or distal surfaces 312 p,312 d, rests against the proximal surface 390 p of the bone 390. In theillustrated embodiment, the distal surface 312 d rests against theproximal surface 390 p. The graft 396 can be moved to its desiredposition with respect to the bone 390 and bore 380 by changing adiameter of the snare loop 322. For example, a force in a directionF_(t) can be applied to the post 334 to reduce the diameter of theadjustable snare 322, thereby advancing the tendon 396 towards theproximal surface 390 p of the bone 390. A person skilled in the art willrecognize that adjusting a diameter of the snare loop 322 to move thegraft 396 can occur at any time during a surgical procedure.

Once the tendon 396 is at the desired location for the procedure, theknot 336 can be actuated to lock the diameter of the snare 322 byapplication of a locking force on the operative suture 340, as describedelsewhere herein with respect to other embodiments. Further, the implant310 can be locked in the same manner as discussed above with sutureconstructs 20, 120, 220, 220′. Optionally, the operative suture 340 canbe removed and/or the post 334 can be trimmed to remove excess sutureonce the snare 322 is in the desired configuration and the procedure isotherwise completed. Alternatively, the operative suture 340 and thepost 334 can be left in place and used to perform additional repairs orserve other purposes at or near the surgical site, such as facilitatingcapsular repair.

The type of graft-bone repair provided for with respect to FIG. 9 isapplicable to many different types of surgical procedures, including butnot limited to an ACL repair and meniscal repairs. The systems, devices,and methods provided for herein can be incorporated into various ACL andmeniscal repairs without departing from the spirit of the presentdisclosure. Some non-limiting examples of ACL repair procedures aredescribed in U.S. Pat. No. 9,387,065, the content of which isincorporated by reference herein in its entirety. Further, a personskilled in the art will recognize a number of modifications that can bemade to the various repair procedures discussed herein, or otherwisederivable from the present disclosure, without departing from the spiritof the disclosure. By way of one non-limiting example, although theembodiments herein illustrate the suture construct 20, 120, 220, 220′,320 passing through tissue at one location, in other embodiments, it canpass through two or more locations and/or two or more tissues. By way offurther non-limiting example, the suture construct 20, 120, 220, 220′,320 can be coupled to tissue using a variety of techniques, for instancewrapping a portion of the suture construct 20, 120, 220, 220′, 320around the tissue. Still further, a person having skill in the art willrecognize that the order of at least some of the method steps providedherein can be altered without departing from the spirit of the presentdisclosure.

Additionally, the procedures discussed are just some forms of proceduresthat can be performed in conjunction with systems, devices, and methodsdisclosed herein. A person skilled in the art will recognize a number ofother ways that the disclosed systems, devices, and methods can be usedin various other configurations and types of surgical procedures. Forinstance, the systems, devices, and methods disclosed herein can easilybe adapted to be used in conjunction with three or more components, suchas multiple tissues and a bone or three or more soft tissues.

What is claimed is:
 1. A suture construct, comprising: a filament loophaving a slidable knot, the filament loop defining an opening having anadjustable diameter; an adjustable limb extending from the slidable knotand configured to adjust the adjustable diameter of the opening whentension is applied thereto to move the adjustable limb with respect tothe slidable knot; a fixed loop extending from the slidable knot, thefixed loop defining an opening having a fixed diameter, the fixed loophaving a first, unlocked configuration and a second, lockedconfiguration; and an implantable body coupled to the filament loop,wherein, when the fixed loop is in the first, unlocked configuration,the adjustable limb is movable with respect to the slidable knot and theadjustable diameter of the filament loop is adjustable, and when thefixed loop is in the second, locked configuration, the adjustable limbis prevented from moving with respect to the slidable knot such that theadjustable diameter of the filament loop is fixed.
 2. The sutureconstruct of claim 1, wherein the filament loop, the adjustable limb,and the fixed loop are formed from a single filament.
 3. The sutureconstruct of claim 1, wherein the implantable body comprises a filament.4. The suture construct of claim 1, wherein the implantable bodycomprises at least one cortical button.
 5. The suture construct of claim1, wherein the fixed loop is rotatable with respect to the slidable knotsuch that rotation of the fixed loop with respect to the slidable knotmoves the fixed loop from the first, unlocked configuration to thesecond, locked configuration.
 6. The suture construct of claim 1,wherein the second, locked configuration is reversible such that thefixed loop can be moved from the second, locked configuration to thefirst, unlocked configuration.
 7. The suture construct of claim 1,wherein the adjustable limb passes through the slidable knot and has asubstantially straight configuration within the slidable knot when thefixed loop is in the first, unlocked configuration, and has a tortiousconfiguration within the slidable knot when the fixed loop is in thesecond, locked configuration.
 8. An implant, comprising: a soft anchorconfigured to be fixated in bone and formed of a flexible construct, thesoft anchor having an unstressed configuration with a first length and afirst diameter and an anchoring configuration with a second length thatis less than the first length and a second diameter that is greater thanthe first diameter; a filament extending from the soft anchor andconfigured to apply tension to the soft anchor to move it from theunstressed configuration to the anchoring configuration; and a sutureattachment loop formed from the filament, the suture attachment loopdefining an opening having a fixed diameter configured to receive asuture therethrough.
 9. The implant of claim 8, wherein the filamentfurther comprises an adjustable anchor loop.
 10. The implant of claim 9,wherein the soft anchor is disposed on the adjustable anchor loop andthe filament extending from the soft anchor is configured to adjust thediameter of the adjustable anchor loop.
 11. The implant of claim 8,wherein the filament further comprises a locking knot configured to havea first configuration in which the locking knot permits the soft anchorto be adjusted and a second configuration in which the locking knotlocks the configuration of the soft anchor.
 12. A method ofmanufacturing a suture construct, comprising: forming an overhand knoton a limb of a single piece of suture, the suture having a firstterminal end and a second terminal end, the overhand knot being in anuncollapsed configuration such that an opening is formed by the limb;inserting the second terminal end of the suture through the opening ofthe overhand knot to create a sliding loop; inserting the first end ofthe suture through the opening to form an eyelet; and collapsing theoverhand knot such that each of the sliding loop, the eyelet, the firstend, and the second end extend from the collapsed overhand knot, with asize of the sliding loop being adjustable by the second end and the sizeof the eyelet being adjustable by the first end.
 13. The method of claim12, further comprising: tying a half-hitch knot around a portion of thesingle piece of suture with the eyelet to form a lock, wherein, uponactuation of the lock, a size of an opening defined by the sliding loopis fixed.
 14. The method of claim 12, further comprising threading asoft anchor onto the sliding loop.
